Comparing continuation rates and side effects of hormonal contraceptives in East Asian and Caucasian women after abortion.
BACKGROUND
The purpose of this study was to determine whether East Asian women had more side effects and a higher discontinuation rate than Caucasian women when choosing to use hormonal contraceptives.


METHODS
This was an observational cohort study of usual care using questionnaires for 2 months after being given hormonal contraceptives following an abortion in Vancouver, Canada.


RESULTS
In the first month, 73 (64.4%) of the 110 East Asian and 86 (80.4%) of the 107 Caucasian women took any of the sample provided (p=.020). In the second month, 52 (47.3%) of the East Asian and 62 (57%) of the Caucasian women used the prescription to buy and take their hormonal contraception (p=.12). Total side effects were similar, but there was more nausea in the East Asian women (23.3% vs. 8.1%) (p=.03) and more acne in the Caucasian women (8.2% vs. 20.9%) (p=.05).


CONCLUSIONS
There may be both physiological and cultural differences leading East Asian women to use less hormonal contraception.
